16sardines, scales and guts removed (ask your fishmonger to do this for you)
sea salt and freshly groundblack pepper
Soak four pieces of clean thick untreated wood in cold water, preferably overnight.
Thirty minutes before you want to eat, light the barbecue. Allow the flames to flare up and die down.
Meanwhile, mix the cucumber, shallot, garlic, oil, herbs and lime juice together in a bowl, then season, to taste, with salt and freshly ground black pepper. Set aside.
When the barbecue coals are red hot, nail four sardines by the tail to each plank of wood. Place the pieces of wood onto the coals (or alternatively on a rack near the coals) and cook for 5-6 minutes, or until the sardines are charred and cooked through.
To serve, place four sardines onto each serving plate. Spoon the salsa alongside.
